To all whom it may concern:

lie it known that i, Divin J. @inclina Tini, a citizen ot thc AUnited States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and useful improvements in Lamp-Burners, of

f which the following is a full, clear, and exactA specification.

This invention relates to improvements in lamp burners and more. particularly to thatclass ot burners adapted to vaporize and burn a liquid hydro-carbon for the production ot' light or heat, and which may be readily applied either to an ordinary or center draft lamp.

A tui/ther object is to provide an improved burner which may be used with a mantle for producing an incandescent light, or quicklyl converted into a. burner vfor producing an argand light.

A further object ie to provide.improved means tor regulating the 'Haine and for supplying air thereto.

A further object is to provide an improved .xi/ick.

A, further object is to provide an improved lamp of this character which will be simple in construction, cheap tov manufacture, and c'liicient in operation.

To the attainment ot these ends and the accomplislnnent of other new and useful objects as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully -de `scribed and claimed and shown in the accompanying drawings illustrating the embodiment ot this invention; and in which:

Fig. l2 is an enlarged detail sectional view ot a portion of the gallerjr and a portion of the chimney in position.

ln the drawings, the same reference nu merals ydesignate similar parts throughout. the several views.

ln this `eiemplitication of the invention,

the burner consiets ot' two ("oncentricaily ar ranged tubes :ltr-21, the outer one of which is of. a considerabljY .larger diameter than the inner tube to torni a wick space therebetween, loih of these tubes are preterabljv provided with slots which regster with each other to lform openings which extend from substantially near the top to the base thereof. These tubeeI are held spaced from each other in any suitable manner, prefer ably by means ota portion ot' one of the tubes adjacent the slots being bent toward and in contact with the other tube, to torni shoulders or supports 2f) at the tops of the slots, and spacing lugs 2st atl the bottom of the slots. rllhis arrangement serves as aA means for closing the ends of the space between the two tubes adjacent the slots to form a housing for the wick, to protect the saine and also to prevent entrance of dust7 etc., and at thesame time permit suiiicient air to pass into the burner tube. yil`he outer tube. 2() is somewhat longer than the inner tube 2l, to torni a projecting portion 25 above the topotl the tube 2l. This projecting portion is preferably reduced above thc end ot the tube 2l to form a circumferential shoulder 2G at. a point' substantially in line with the top of the inner tub(` 21.

A suitable wick 2T is placed ,within the Space between the tubes 20H21, and said wick is preferably biturcated, one ot' the bifurcated portions standing on each side o1" the slots or apertures 22, and said wick is oi" sntiicient length to project below the bottoni of the burner and extend into theI basin ot" thelamp in the ordinarj7 manner. The bodtY ot the wick beyond the bit'urated portions is of such a length that the base of the bifurcations will rest upon the shoulders or supports 23 between the tubes 20-21 and the top 28 thereof will engage the shoulder 26 formed bv the projectingl portion25, on the tube 2f). and project slightly abovtlhe top oi the inner tube 2l. tor a purpose to be Vso set forth. W'ith this arrangement it will be' seen that when in position the wick 27 will be completely housed and protected andr that by means of the base of the bifurcations resting upon and being engaged by the Ishoulders` or supports it will be i1npossible for the wick to become displaced or be forced or accidentally drop into the lamp basin. Any suitable wick may be employed such as a tubular wick cut to form the bifureated portions or ay specially prepared wick may be used.l

A screw threaded portion 29 may be formed on the outer tube 20, or .secured thereto, which serves as a means by which the burner may beattached to the lamp basin. The top 3() thereof is preferably cup shaped to serve as a receptacle to catch any of the oil which may escape from the burner.

A suitable rino' or collar 3l is provided with an inwardly projecting portion or flange at its upper end and a laterally projecting circumferential portion or bead 325 located preferably adjacent the flanged end thereof. A supplemental tubular wick 35 is removably and reversibly held within the ring or collar 31 so that the upper edge 556 thereof will engage and rest under the flange and with its' bottom terminating substantially flush with the lower edge of the ring or collar. This ring o1` collar Iis of such a diameter as to snugly lit within the projecting portion 25 of the tube Q0, and is of a length that when the projecting por- `tion or bead 33 thereon rests upon the top of the portion 25,'its lower edge and also' the edge 21T of the supplemental wick 35, will rest upon and engage theedge 28 of the wick 27, so that the supplemental wick will be Supplied with oil byrmcans of capillary attraction, from the wick 27, and the ring or collar may beheld or locked .from displacement in any suitable manner, preferably by means of pins or lugs 34, projecting from the periphery thereof, which are adapted to enter ordinary bayonet slots or grooves 28 in the portion 25. l f desired, any suitable material 38a, such as paper or the like may be secured to the periphery of the supplemental wick S5, for preserving and causing the same to maintain its shape. lhns it will be seen that when it' is desired to remove the supplen'iental ywick 35, the ringl or collar 31 is first removed from they portion 25 of the tube 20. after which the wirk may be easily slipped out of the collar or ring.

Sliding within the inner tube 2l of the burner and of a diameter to contar-t with said tubo is a hollow tubular regulator member El). the upper end ofwhich may be flanged inward as at 40 if desired. This men'xber is provided with a web comprising a bod \Y 4l supported by spared arms 42, and adjacent the base ot the. burner, but remote l from the end thereof is a similar web 43' provided with a bearing 44. Passing through the body portion 41 of the web and secured thereto is a tube 45, the upper extremity of which is preferably above the web and adjacent the top of the tubular regulator member 39, and said tube moves with the member 3?. The lower end of the tube passes through the bearing in the web 43 and-is of a length to prevent the end thereof from disengaging the web 43 when the tubular member is at its extreme highest y point. This member 45 is preferably hollow for the sake of lightness and closed at its lower end to prevent anything' from passing therethrough and into the lamp basin. Thus it will be seen that when the tubular member 39 is raised or lowered the member 45 will vserve a guide to prevent displacement and to maintain said memberr 39 in proper position. Any suitable means may be en'iployed for raising and lowering the tubular or regulator member. A simple. and etlieient means for accomplishingthis purpose, which will now be described comprises spaced arms 4U secured to the burner and are preferably connected at ktheir top as at 4T. .\n arm orlever 48 is pivoted between the arms at a point intermediate its own length, and one end thereof projects through one'of the slots 22 in the burner with its eX- tremity standing` within a slot 49 in the tubularguide member 45. The extremity of the arm or lever 48 is bifurcated so, as to l-oosel y receive a transverse pin or bartl eX- tending across the slot 4S). The other end of the arm or lever may project for anysuitable distance beyond 1ts pivot point. and

attached thereto is a flexible or operating member 5l. The weight of the regulator and `guide members is sufficient to hold the free end of the arm or lever 48 ele\iated. 'lhus when the flexible or operating member 5l depresses the free end of, the arm or lever the regulator member 3!) will be raised and when released will drop back to its normal position. ln order to prevent the regn-y lator and guide members from being thrown out of position by depressing the free end of the arm or lever too far, a suitably located stop 52 may be arranged within the path of movement of the arm or lever 4S, the rotary iiaxial uioven'ie'nt of these menibers beiner )revented b the bifnreated end b of the arm or lever 48, standing within the lslot 4S) of the guide member 45. The arm or lever 4B may also be operated by means of a regulating or adjusting screw 5Fl which passes through the (zonnet-tingportion 4T of the arms 46 and is adapted to engage and depress the free end of the arm.

A suitable spreader or gasitier 54 is renxovably secured to one end of a stem 55 in any desired manner such asby means of a Screw or bolt. Till. 'lhe periphery of this iso @aeree HV v spreader or gasltier if; notched to form Wings 57 whl'ch' are bent at an angle to thebody Vportion 54, and to a position to slightly ber etti, eo' that the :shoulder (it) will rest; upon the edge thereof. This Shoulder 39 isv located" at such a pointA that'J the spreader or 'gasltier will be properly epaeed troni the top ot the regulator inenlber 3S).

.20. L 'tt, ot the naine diameter, and which is ar- 'flange 'or basey (S7.

The gallery comprises a` perforated base or body portion (it) which is preferably constrneted in the 'torni ot" a basket. eontrartcd atv ite lower end, as at (il. and adjacent its upper end is provided with arios (32, snpifiorting a centrally disposed ringor collar ranged to register with the eoi'xtracted portion (3l. and'these regietering portions are adapted to receive .the endot` the burner. The contracted portion til being' adapted to meagre and rest upon `a Suitable Shoulder G4 'formed on the burner, and serves as afnieano for supporting the lgallery. The lower ein trelnity of the body portion is preferably flanged outward to serve a bane upon which the gallery rests when removed .from theburner. lt' also `serves ae a shield troni the tlanle. when replacing' the gallery on the tube.'

.l conical burner shield or hood 30 is provided with a lateral projecting pertoated rthe extremity ot the arms (32 and the periphery of the bane or flange o7 being' adapted to be secured to the body t5() at a point :nljaeenty the chimney holders4 (38 in any desired manner, preferably by means et Hanging' or crimping the body portion over the edges thereoic as shown at ($9. The top of. the shield or hood tti is disposed to stand adjacent to and slightly above the top ot the supplemental wick 35,

. and the body thereot is so .spaced t'roin the burner tube that air will be d awn between the shield or hood and the burner, and be directed afrainst'the iaine. The. body portion (it) ot' the tgallery is provided with a :series ot pertoratons 7() above and adjacent 'the flanged base (37 ot the hood or shield oth and the latter is provided with spaced upwardly projecting portions or lugs Tl upon which the chimney or globe T2 resten as more clearly shown in Fig. ll. 'lhus it will be seen that additional air will be permitted to enter the pertorations T0 and pass beneath `and into the ebininey o1' `globe 72.

it suitable mantle support is provided with a conuzl base T?) to which the extremi- 4ties ot the mantle au )iortinif armo or wires 74 artl seeured. ".he upper portion ot this 55 is provided with a T6, and said enlarged portion is provided with corr-ugations 7T arranged-longitudinally thereof and Said corrugations-extend troni one shoulder and terminate short of the-'top ot' the enlarged portions. Passing through the yshouldered portion 7G are a i" lity ot apertures or holes 78 one ot wlorh pl-'eferably 'arranged adjacent the. end ot each of the eorriurations. The base ol this inantle support' is adapted to be passed over the burner shield or hood (to, so aa to rest upon the 'tlanp'e G7' and with the portion 73 engazggiiigil ,said hood or shield. The enlarged portion 75 stands adjacent and projec s slightly above the hood or shield to "torin a. space thereljietWeen, into which air passen through the opening-a or apertures 78 and is directed against the thune. The lower extremity ot' the mantle 79 rests against the periphery ot the corrugated portion and extendsI across the corrugatione therein in such av manner as to perlnit air to enter between the 4periphery ot' the corrugated portion and the mantle 79. lilith such an arrangement sutlieient air will be directed against the spreader or gasitier and by thie manner of admitting the 'air togetlier with its contact with the heated parte, the air will beeoine euperheated, thereby insuring perfect colnbuetion and preventing carbonization ot the niantle. lt the lnantle should not be perfectly straight or it to' any other reason the vthune Should make one side of the inantle more incandescent than the other then the weaker eide would `naturally carbonize a little. lith this ar ang'enient and in order to overcome this difficulty, the coin plete gallery may be rotated about the..`

position .so that the thune which will burn the carbon ott'.

lihen it is desnd to use thinl improved burner with a lainp which is not` a conter draft lainp, the lower end ot' the inner tube 2l ot theebln'ner may be closed in any desired manner.. but. preferably by .nleans of a rap or plug 8U titting` therein which may be secured in any desired nlanner butl preterably by means ot an inter-engaging lug Hl and slot S2 termine` the ordinary l'iayonet: joint (see Fig. 11). This cap or pluie` may be provided with the neressary aptnturo S?, t'or the end ot the guide or tubular nieinber to pass through. vWhen using` the saine with ya center dra'lit lainp the plug' or cap S() is removed and a ineniber or nozzle 8l haring a reduced portion 555 to torni a.

shoulder Htl may be usetL or any otliwr conmay be employed. ln this evelnilitication the body portion ot' the inelnlier is applied over the end ot' the central an' supply tube.

and held in any desired manner and the reduced portion F45 1:4 nmerted into the lower end of the inner tube 2l of the' burner so that the end thereof will rest upon and be supported by the shoulder'StS. e

The exeniplitication shown in Fig. 1 is employed with a mantle for producing an incandescent light, the air entering and being directed by the various passages against the spreader or gasitier 54. The vapor being ignited and burned adjacent the inner face of the supplemental wick 35 at the top thereof and is deflected or spread by'the plate 54: uniformly against the inside of the mantle. The thune being regulated by means of the .'slidingl regulator 3S), operated by the arm or lever ftS. When it is desired to extinguish thetiame the regulator is thrown suddenly upward so that the upper end thereof Will projeetabove the upper end of the supple-` mental wirk 25 which will cut out tibet-lame; .ln this form of the invention thesupplemental wiel; 255 does noty burn but only the fuel burns, whieh is raporized or ganitied adjaeent the faee'of the wick.

lVhen it is desired to use the burner as an Argand burner the mantle and support. together with the spreader plate or gasitier :it are removed. vWith this form of burner it is ueeessary to reduee the pressure of the air whieh is supplied to the burner. This may be aeeomplished it the gallery is raised to spare the hood or shield (3S farther from the end of the supplemental wiel( 35.

Any suitable means may be employed for supporting' the gallery in its raised position, but a simple `and etlieieut means for this purpose eomprises a ring or collar Si, which surrounds the burner and rests upon the `shoulder (Si, and upon which the gallery rests. To apply this ring the gallery is reik moved from the burner, the ring 87 slipped over the end ot the burneriand against the shoulder (it, and the gallery then replaeed. 'lhe operation of the parts are the same in this exemplitieation with the exeeption that instead of i'aporizing` the oil and burning` the Vapor, the supplemental wieh 3.3. is itself burned but supplied with oil trourthe main wirk i in the same manner. 'l`he same re' sult ma)r be :n'eomplished it the chimney` is raised so that the openings i() in the holder will not he restrirted. i
